I am very unclear about what your question is?

We've been here before...

Why are you putting the X/Y values in a struct, when you don't use it for the call to WindowFromPoint?

Drop the struct if you aren't going to use it:

HotKeySet("{ESC}", "_Quit")

While 1
    Sleep(100)
    ToolTip("")
    $hwnd = WindowFromPoint(MouseGetPos())
    ToolTip($hwnd)
WEnd

Func WindowFromPoint($aPoint)
    $aResult = DllCall("User32.dll", "hwnd", "WindowFromPoint", "int", $aPoint[0], "int", $aPoint[1])
    Return $aResult[0]
EndFunc   ;==>WindowFromPoint

Func _Quit()
    Exit
EndFunc   ;==>_Quit

Hix, i want use "DllStructSetData". Please help me

What are you even doing with the struct (from your example) that you need one?

OK, if it's just an exercise, this works:

HotKeySet("{ESC}", "_Quit")
Global $Struct = DllStructCreate("int x;int y")

While 1
    Sleep(100)
    ToolTip("")
    Pos()
    $hwnd = WindowFromPoint()
    ToolTip($hwnd)
WEnd

Func Pos()
    DllStructSetData($Struct, "x", MouseGetPos(0))
    DllStructSetData($Struct, "y", MouseGetPos(1))
EndFunc   ;==>Pos

Func WindowFromPoint()
    Local $x = DllStructGetData($Struct, "X")
    Local $y = DllStructGetData($Struct, "Y")
    Local $aResult = DllCall("User32.dll", "hwnd", "WindowFromPoint", "int", $x, "int", $y)
    Return $aResult[0]
EndFunc   ;==>WindowFromPoint

Func _Quit()
    Exit
EndFunc   ;==>_Quit

In your original struct (copied from an unrelated help file script I suspect), you variables were named var1, var2, etc., which is why they don't work when you call them by "X" and "Y".
